There are a lot of possible irreparable or expensive to repair problems with that table and / or arm. If the table is truly trashed, then maybe a different table is in order as suggested above. My opinions on a "new" table stand on their own +/- merits.
You should carefully consider the comments on this tread, listen carefully to tables and arms, and make up your own mind as to what is the best option for you.
